I'm in the same boat as you I am having my blood drawn for hyperglaucemia(sp) and she also is buying having them draw more blood for a test.

If you haven't smoked within about a week I think you'll be fine. But I am not familiar with blood tests. But I don't think the doctor can tell your mom.
soxsuk6432 Reviewed by soxsuk6432 on . Doctor? So my mom is taking me to a doctor to have some blood work done. She says it's for nutritional purposes because i'm a vegitarian but I have a feeling she's going to try to get a free drug test in there because i got caught last october and I think she's still suspicouse. So can a doctor tell her that there is THC in my blood or does that go against a law or policy? Rating: 5
